Ubuntu :: 11.04 Frequently Crashes / Why Is So - Fix It?
Sep 1, 2011
Anywhere from 2 -> 6 times a day, my computer will freeze up. If any audio was playing, it will repeat the last few seconds over and over again.
I've been dealing with the problem for a couple of months now, with no solutions.
It can happen anytime, but it tends to happen on my screensaver about 50% of the time after I've locked my computer and during the early morning (12am onwards) when I have a full-screen video playing, but it's never done it at night in the same circumstances.
I am confused and just can't figure out the problem.
Computer info:
Mac Mini (2010) 2.4GHz
8GB RAM
Dual 24" Monitors @ 1920x1080.
Ubuntu 11.04 64-bit.

I just upgraded to Natty on a (almost brand new) HP pavilion dm4t. I'm finding that it crashes pretty frequently, in a variety of ways that might or might not be related.
1) Sometimes (every 2-3 days) it will just blink out and go back to the login screen. This usually happens within a minute or so of logging in. If I log in again after this, it will usually crash again. A restart of the system typically will make the problem go away for at least a few sessions.
2) If I leave the computer on for a while, the screensaver will freeze and nothing can get me back to the desktop. Processes seem to still be running behind it (I left some music playing once and the music continued to play, but the screen was black and I couldn't get back to my desktop - I had to do a hard shutdown)
3) A perhaps unrelated problem, every ten sessions or so when I log in the indicator applet will be gone and an error telling me that indicator applet failed to load (or something to this effect)
Btw I'm using ubuntu classic rather than unity (just because I like it better). I haven't used Unity enough to know whether these problems also occur with it.

I recently switched from windows 7 to ubuntu 10.10 on my Gateway NV56 laptop. I previously had used wubi on it and had no problems, but with this installation it frequently crashes to a black screen and I have to reboot via the power switch. alt+sys-req+REUISB does not work, and I have lost a lot of data to this.
My hardware is as follows
-AMD turiion X2 RM-75 2.5 GHz dual core processor
-ATI Radeon HD 3200
-4 GB memory
-500 GB SATA HDD
-6 GB Ubuntu
-41 GB linux swap
-453 GB data

Recently pcmanfm crashes more frequently then before. Each time it occurs, I cannot open another instance of it until I reboot my desktop/laptop. But this is not possible if I happen to be doing some long computational work. I have been using it with fluxbox for two years already, and previously I simply reopen another new window and get on with my work.

I started using 10.10 a few months ago and had very few problems aside from a few minor issues with Wine. I frequently used Skype under 10.10 and it ran perfectly with no issues whatsoever.
Recently I upgraded to Ubuntu 11.04 and well... basically things have just gone downhill from there.
Over the past few days Skype has been ridiculously unstable, I'll be talking to somebody using text chat and it will essentially freeze up. These freezes can occur within minutes of starting Skype and are very infuriating. I am still able to type and send messages but the "message not sent" icon will appear next to each of them and the timestamp on each message will be identical (the messages in question will not send even after a restart of Skype). This problem will persist until I force-quit the application, closing it normally will not work and often I have to restart my computer entirely before it will work again.
I have tried updating to the latest version of Skype to no avail (if anything I think it has made matters worse, but that may just be my imagination.)
I'm not particularly command savvy, just posting on the off chance that anybody has encountered the same problem or has found a relatively simple fix. I don't really want to have to re-install the entire OS just to roll back to 10.10.

I'm using Ubuntu 6.06 and Apache.I connect to the machine via FTP. It seems as if the connection times out every few seconds. If I u/l a file it will take 15 seconds to connect. Once that connection is open I can u/l more files instantly. If I wait a few seconds it closes, then I have to wait another 15 seconds for it to reopen. Any ideas how to make it not time out so frequently?

I'm looking at conky and my cpu frequency is fluctuating really fast (in a relatively narrow range) but from second to second I can see a 2-3 degree change, is this even possible? It seems like the sensors aren't working right if they are showing changes that fast.

I'm having a issue. It first started a few nights ago, and after booting from the live cd and reading around, I saw it mentioned somewhere that it might help to update GRUB. I did this using sudo update-grub. This took care of the issue, with an unexpected, but not altogether unwanted result: instead of having to choose a temporary boot device to boot on to the external drive Ubuntu is on, I got a grub menu which showed the the OSs for both HDDS. I thought all was fine, but a few days later, same thing. Updated grub again, and all was okay. Tonight, it happened again.
When I try to update grub now it says:
Code:
ubuntu@ubuntu:~$ sudo update-grub
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
Here's the result of the boot info script.
Code:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #1 for (,msdos1)/boot/grub.
=> No boot loader is installed in the MBR of /dev/sdb .....

I have a new ubuntu 10.04 install, it is the third that I have done recently. On this particular install (unlike the others) the screen goes unexpectedly blank at seeming random intervals and any motion restores the screen. It is acting like a screen saver with the blank screen option set. My screensaver preferences are set to use a screen saver 'for a 7-minute idle period. The lock screen option is off. For AC power management never is chosen for "put computer to sleep" and 30 minutes is chosen for the "put display to sleep" option.
This is a compaq presario desktop.

Under 9.10, my laptop frequently freezes up and has to be hard-reset. At first I thought it was a Firefox issue because it happens most often when I'm on the web, but the computer also crashed on me while doing things in Synaptic, so it must be something else. I have an HP Pavilion z5000 with an Ati Radeon 9600 Mobility, 1.25 GB of RAM and 120 GB hard drive.

I'm trying to figure out how to use wget to save a copy of a page that is frequently updated. Ideally, what I'd like it to do is save a copy of the page every minute or so. I don't need multiple copies; I just need to know what the most recent version was. Also, if the page disappears for whatever reason, I don't want it to save the error page, just wait until the page is up again.

I upgraded to Karmic the other day and my Wireless Internet has been disconnecting every hour or so. I had the same problem on Intrepid but I managed to fix it somehow. After disconnecting, it will reconnect after a few seconds.

I was wondering if there is any tool or program that stores a copy of frequently used files eg. Binarys, program library's etc. in memory so when they are requested by the OS they load instantly. I'm asking because I have a system with plenty of ram but very slow hard disks. Having programs like opera and java/eclipse load from ram would greatly speed up their start time. Ideally they would be loaded into ram in the background after I log in. Of course all writes made to these files would have to be made to the files on disk for obvious reasons.I don't want the entire OS in ram because it will not fit, just frequently accessed files.

programs (especially Firefox, though I haven't used other programs much) stop responding rather frequently without warning and after some time they just start responding again. Apt-get also takes ages to unpack stuff when I'm upgrading/installing something, that might be related. According to top there is barely any cpu usage at all during these freezes. I had this issue on a stock Lucid install. When Maverick came out, I tried that one, and the issue still existed. On a fully upgraded Maverick system, it's still there as well. Windows works without a hitch, as does Ubuntu running under a VM on windows.
System specs:
CPU: Phenom 2 x4 945 @ 3 GHz
GPU: Radeon HD 5770 with fglrx
4 GB of ddr3 ram
Motherboard: Asus M4A89GTD PRO
Hard drives: 2 WD 1.5 TB drives running on a fakeraid 1 array

I'm using 10.04.2, and I find that whenever I'm trying update (whether using synaptic, or command-line apt-get), the package download starts off fine, but after downloading a few files (usually only 4 or 5), the next partial (ongoing) downloads become corrupt, all the remaining downloads stay in the partial folder and finally apt-get gives a size mismatch error .I'm forced to watch the update progress the entire time and wait for the downloads to corrupt (at this point the progress bar stops at say, "Downloading file 4 of 70" but the details show subsequent files are being downloaded)the update process and clean the /var/cache/apt/archives/partial folder (NOT the archives folder, or all the packages will have to be downloaded again). Then I restart the update and it picks up after the last successfully downloaded .deb.
Effectively, every such iteration downloads 3-5 .deb files successfully, and corrupts the remaining. Needless to say, if I'm upgrading 50 packages, it gets really frustratingI faced this problem even on new installations on my system as well as a friend's. Lucid, Maverik, Natty all have the same problem. By new installations, I mean on the very first boot, I setup the network (I'm behind a proxy server in a university) and that's it. I tried Linux Mint and it had the same problem.

I am using lenny on an Intel 5200 dual core machine with 2 GB RAM
The problem facing is sometimes The dialog box "The sustem will immediately shut down" is shown and goes to power off. I thinks it is connected with a hardware problem. But It is difficult to trace out what is the problem and in which part of the hardware it is.
The motherboard of this computer was complaint and it was replaced by the company (It is seen than it is the same motherboard with one IC replaced)
The problem is difficult to identify since it is not happening every time. When the service persons are here it is working fine. But when i works with the computer seriously, the problem arises - mostly in night. I have checked the power, voltage etc - everything fine. Also it is in linux, service persons don't pay attentions to solve the problem.
Is it the problem with RAM? It is a new RAM. Even if it is bad I can't replace it because it is working! and in windows (service persons check it with windows only)

Recently I installed Arch on my computer. There are now three systems on it:XP,Ubuntu,Arch.I choose to share the same disk space for swap and /home in the two systems.The installation went well except some problems with Grub, and I managed to made it work. These days,when I start my computer and choose Ubuntu,there always displays a short message about /home disk checking or some problems about fstab. I don't know why. When I login to the system, it works well all the time.

I am far too often getting connections dropped when trying to load web pages from my local server. From my mac running Safari I get the error message "Safari can't open the page...because the server unexpectedly dropped the connection." From Firefox on my Ubuntu 0.10 desktop it opens the window that says "You have chosen to open index.php..." and ask if I should edit the file or save it. When I tail the apache2 access.log it shows the previous successful page load but the one that failed is not mentioned. In error.log I get some stuff I don't understand, except the last line which says aborted:
b7819000-b781b000 rw-p 00000000 00:00 0

I am running FC12 64bit. Frequently the system hangs usually one app - Thunderbird. If I have Firefox up also, it seems to run fine. The light indicating disk access is on almost constantly. Is there a way to find out what process is accessing which disk? I have 4 hds installed - 2 IDE and 2 SATA. I am having a similar problem trying to do a reboot - it does not reboot within 15 minutes. I need to hit the reset button.
